WINDOW.

Application led August 18, 1920. Serial No. 404,365.

To all whom it may concern. i,

Be it known that I, JOSEPH SYLVAN, a citizen of the United States, and a resident of Chicago, in the county` of Cook and State of Illinois, have invented certain new and useful Improvements `in Windows and' I do hereby declare that the following is a full, clear, and exact-description thereof, reference being had to the accompanying drawings, and `to `the .letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in windows and consists of' the matters hereinafter described and more particularly pointed out in the appended claims. `The `primary object of the invention is to provide a windowwherein both sash are so connected together that upon opening or closing of one sash a like movement is `imparted to the other sash.

Another obect of the invention is vto so arrange the parts that when the window sash are in their open position the incoming air is deflected upwardly toward the ceiling of the room.

Other objects of the invention as well as the many advantages thereof will more fully appear as I proceed with my specification.

In the drawings- Fig. 1 is a vertical section through a window embodying my invention with the sash in a closed position.

Fig. 2 is asimilar section with the sash shown in an open position.

Figs. 3 and 4L are horizontal detail sectional views, on an enlarged scale, taken on the linesI SH3 and 1 -4: respectively, of Fig. 1.

Referring now in detail to that embodiment of the invention illustrated in theaccompanying drawings, indicates a `sheet metal window frame and 6 and 7 indicate the4 top and bottom `window `sash thereof respectively.

The window frame 5 comprises upright side members 8, a horizontal top member or lintel 9 and a horizontal bottom inem- Vtween said side members and webs.

ber or sill 10. The side members 8 each have a centrally disposed, substantially wide web 11 which is spaced inwardly from the body part of each side member and is connected thereto, short of the margins 12, byflanges 13 to provide inwardly and out'- wardly opening grooves 14 and 15 respectively. At the top end of each web 11 of the side members 8 and preferably nearer the outer than the inner margins 12 thereof, is provided a vertically disposed slot 16, which is bound or defined on the inner surface of the web by a reinforcement 17. (See Fig. 3.)

rlhe top member of the lintel 9 of the frame has a ledge 18 which depends from `its outer margin, and in the bottom surface of said ledge is adownwardly opening groove 19. The sill is provided on its ,top surface near its inner edge, with an upwardly and inwardly extending ridge or rib 20.

The top sash 6 is of the tubular sheet metal type and comprises top and bottom horizontal members 21-22 and upright side members 23, all of which are constructed to provide suitable channels to receive the pane 24. Y

The side members 23 of the top sash are spaced a short distance inwardly from the webs 11 of the frame and along the outer edge of said side members are hook flanges 25 which bridge and close the spaces 26 be- Said hook flanges normally engage in the outer grooves 15 (see Fig. 3) of the frame when the sash. is in the closed position shown in Fig. 1. `The top member 21 of the sash has inner and outer upright tongues 27-28 which act to form a tighty joint at the top of the sash, the outer' tongue normally engaging in the groove 19 in the ledge 18 for this purpose. The bottom member 22 of the sash is provided on its inner bottom marginal part with a groove 29 to receive a tongue on the top4 member of thel bottom sash. In the hollow side members 23 of said upper sash, near their inner faces, are

secured upright flat bars which extend through and beyond the top and bottom members 21-22 of the sash.

The bottom sash 7 comprises top and bottom horizontal members 231-32 and upright side members 33, all of which are hollow and are constructed to provide suitable channels to receive the pane 34.- The Vside members 33 ot the bottom sash are spaced a short distance inwardly from the webs 11 ot the side members ot the traine and along the inner edges of said side members are hook flanges 35 which bridge and close. the spaces 26 between the said side members and webs 11 and normally engage in the. inner grooves 14 when `the sash is in its closed position as shown in Fig. 1. The top I'member 31 ,ot the sash has a tongue 36 on its outer bottom edge adapted to extend into the groove 29 onthe Abottom .member 2 2 of the top sash to form an ,airtight joint between them in the normal closed position. Thetop member 31 alsohas a handle 37 by which the sash is actuated and also on said top member and on the bottom member of the top sash are co-acting locking devices 38 to lock the window sashtogether- The bottom member is 'formed to provide along its front bottom edge, a downwardly opening groove 39 lwhich receives the; rib 2O on the sill to provide a pivot or hinge between the said bottom vrsash 'and sill. In the hollow side members of the sash 7 near their outer faces are provided upright fla-t bars 40 which extend through and beyond the top and bottoinmembers of saidv sash. Links 41 arranged in pairs connect the top ends of the bars 40 ot the bottom window long enough to extend into theslots 16 in the'webs 11 before mentioned.

The operation of the improved window is as follows Assume that the .fsash 6 and 7 are locked `in the closed position shown in Fig. 1. The coacting locking ydevices 38 are actuated to'unlock the` sash and `the voperator grasps the handle 37 ontheY top member of Ivthe'bottoin sash Vand pulls the ribs 18 as a pivot. As'the sash 7 thus swings, a vertically downward movement is vimparted to the top end ot the top sash owing to the guided movement ofthe pins 43 in the slots 16. As the top sash moves to thetop edge of-.the bottom sash, which having side. members, top and:bottomsash room, apart of this air entering above the topof the ,top` sash. Even vshould rain renter atithisypoint -it will tall -fuponlthe bottom sash to be directed outwardly by the slope 'orinclination thereof.

To close the windows, a push is imparted through the links 41 will lift the top end of the top sash Iand its.. bottom end will swing inwardly under the action ot the links 42 so that both sash are again in the position shown in Fig. 1,l after whichthey are locked together.

The yimproved window` is lespecially adapted for u se inl -tactoryandoliieel buildings on -account of the ventilation it. alfords. -Bothsash open and closeftogether and when open alford a proper Ventil-ation of the room and whenv closed preventslthe entrance of drafts. As no expensiveweights or-fsashcord connections .need vto be.=n1ade, itis simple inconst'ruetioniand easy to install vand remove for the pur/pose of .painting and cleaning.

lVhilejn describing my invention I have referred to certain details of: mechanical construction and arrangement vot. parts, I do not wish to be-limited thereto except as may be pointedy out inthe appended claims.

I claim as my invention f1. In combination with a ;wi-ndow trame having slotted side members andl a' sill hav- 105 ing a ribthereon, top and bottomsash in said trame, the bottom sash having a groove in its bottom member to receive said rib to'provide a pivotal.engagement for the -bottom 'sash withlsaidlsillflinks arranged 110 in pairs and connecting` thetop. and bottom ends of the sash together and pins providing the pivotal -conncctioir between said links and sash, the pins connecting. the links withthetop end otY the top sash, extending into the slots inthe sidefmen'ibers ot the frame.
